Model and configuration

Parameter Details
Application and enclosure Application B: horticultural lighting; catalog status: under development. Enclosure: standalone.
Configuration selection This application/enclosure code does not identify the three extension-card slots. Confirm the complete ordering configuration and the application firmware; the shared platform connector list does not mean every interface is enabled.
Extension-card coding P = PMBus card (two PMBus v1.1 ports); C = CANBus card (two CANBus 2.0B ports); R = RS-232/RS-485/USB card (including two USB ports); # = blank slot. Card capabilities and active connector functions depend on the application. The separate -R after the application code denotes the rack-mount enclosure.
Application availability The catalog identifies this application code but does not provide a completed connector-function matrix or a supported-equipment list for it. Obtain the application-specific specification and supplied configuration before commissioning.

Monitoring and operation

Parameter Details
Touch display 7-inch TFT LCD, 800 × 480 resolution, capacitive touch panel. The application determines the status screens and commands available.
Monitored information The platform can display connected equipment’s voltage, current and operating status. The catalog lists input/output voltage, output current, temperature and fan speed; actual measurements are application- and device-dependent.
Local controls Touchscreen operation; the dedicated rack hotkeys and rotary control are not part of the standalone arrangement.
Indicators and buzzer Green: power-on/normal conditions; red: fault/abnormal conditions. The catalog describes a steady red fault indication. Audible alarms, with mute.
Ethernet and web interface IEEE 802.3, 10/100BASE network. The platform supports TCP/IP, NTP, SMTP and Modbus TCP; the web server provides application-specific system status, parameters, data logging and download. Configure access and settings using the applicable user manual.
Data and event logging Date/time-stamped data and event logs require an installed SD card. The platform supports SDHC cards up to 32 GB.
Clock retention The RTC uses supercapacitors with a stated retention of only 7 days. Readjust the date/time after a longer unpowered interval.
Language and firmware English, Traditional Chinese and Simplified Chinese interfaces. Firmware updates are supported through SD card or Ethernet; use firmware intended for the actual application and follow its update procedure.

Application interfaces and wiring

Parameter Details
Connector-function limitation Relays, analog I/O, digital I/O, PMBus, CANBus, RS-232 and RS-485 are defined by the application. No enabled-connector matrix is published for this application code; do not wire or use a connector based on its physical presence alone.
Relay rating Platform provision: four user-programmable relay channels, rated 30 V / 1 A. Application support must be confirmed.
Analog I/O availability The shared platform specification lists five 0–10 V analog outputs and five 0–10 V analog inputs with 12-bit resolution. Their availability is not established for this application; obtain its application-specific connector definition.

Input, environment and standards

Parameter Details
Input voltage and frequency 85–264 VAC, 47–63 Hz; 120–370 VDC. Use the published operating range for the supplied unit; the AC connector labels do not establish a DC polarity assignment.
Input current 0.6 A at 115 VAC; 0.4 A at 230 VAC.
AC input connector Pin 1 = AC/N, pin 2 = AC/L, pin 3 = FG. Follow the input and grounding instructions for the supplied controller.
Operating temperature −25°C to +60°C. The LCD may freeze below −20°C; this display limitation remains applicable within the controller’s stated operating range.
Storage temperature −40°C to +60°C.
Vibration 10–500 Hz, 2G, 10 minutes per cycle; 60 minutes along each X, Y and Z axis.
Safety standards IEC 62368-1 and BS EN/EN 62368-1 approved.
Withstand voltage Input–output: 3 kVAC; input–FG: 2 kVAC; output–FG: 0.7 kVDC. CN36 and CN37 are considered output for these tests.
Insulation resistance Output–FG: 100 MΩ at 500 VDC, 25°C and 70% RH.
EMC emissions BS EN/EN 55032 (CISPR 32): conducted Class B and radiated Class A; BS EN/EN 61000-3-2 and -3-3.
EMC immunity BS EN/EN 61000-4-2, -3, -4, -5, -6, -8 and -11; the catalog also lists BS EN/EN 61000-6-1 with BS EN/EN 50082-2 in parentheses, light-industry level, criteria A.
System integration The controller is a component. Catalog EMC tests cover the controller alone without connected control equipment; reconfirm EMC compliance in the final assembled equipment.

Dimensions and mounting

Parameter Details
Dimensions 245 × 70 × 164.2 mm (L × W × H), standalone format. Use the complete mechanical drawing for mounting and connector clearances.
Mechanical drawing Catalog general dimensional tolerance: ±1 mm. The standalone drawing identifies four M4 mounting positions with L = 10 mm; use the specified mounting arrangement and appropriate fasteners.
Mounting Standalone wall, DIN-rail or desktop mounting. Wall cavity: 230 mm wide × 135 mm high × 52 mm deep; wall diagram uses M4 × 25 mm screws and M4 × 20 mm plastic wall plugs. DIN-rail bracket fits TS35/7.5 or TS35/15 rails; the rail is not included. The desktop drawing shows a 120 mm footprint.
Mounting accessories Catalog accessories: 1GG2DRP14A DIN-rail mounting bracket and 1GG2MHS094 desktop mounting stand. They are included with the corresponding standalone models; confirm the supplied package. The catalog item numbers do not specify supplied quantities.
Unit mass 1680 g, catalog packing reference per unit (1.68 kg; 8 pieces / 14.4 kg / 2.14 CUFT). This is not a separately declared measured net mass.
Manufacturer warranty reference The catalog states a five-year manufacturer warranty, subject to its applicable terms.
